Native table 'performance_schema'.'???' has the wrong structure

Question

I am getting the following:

Native table 'performance_schema'.'file_instances' has the wrong structure Native table 'performance_schema'.'cond_instances' has the wrong structure Native table 'performance_schema'.'rwlock_instances' has the wrong structure Native table 'performance_schema'.'mutex_instances' has the wrong structure ... 

And on it goes These errors come up when I restart MySql. It seems to cause MySql Administrator to become unstable, I get a lot of:

"MySQL server has gone away" 

Answer 1

Try following command in shell (the root user here is the mysql root user, not the system root)

sudo mysql_upgrade -u root -p  sudo service mysql restart 

Make sure to restart mysql after running this (All credit to @Mikepote in the comments.)
